Complete Example for Error Handlers Other Versions Visual Studio 2010 .NET Framework 4 Visual Studio 2008 This code example includes elements for both page-level and application-level exception handling. Code Example Files The example consists page level error handling in asp.net example of the following files: Web.config Global.asax Default.aspx ExceptionUtility (to be put in the App_Code folder) GenericErrorPage.aspx HttpErrorPage.aspx Http404ErrorPage.aspx DefaultRedirectErrorPage.aspx Web.config The following example shows the Web.config file. The customErrors section specifies how to handle errors that occur with file types that are mapped to ASP.NET, such as .aspx, .asmx, and .ashx files. (In IIS 6.0 and in IIS 7.0 in classic mode, static content files such as .html and .jpg files are not mapped to ASP.NET.) The settings in the example customErrors section cause any unhandled HTTP 404 (file not found) errors to be directed to the Http404ErrorPage.aspx file. These HTTP 404 errors would occur if a request were made for an .aspx file, .asmx file, and so on and if the requested file did not exist. All other unhandled errors in ASP.NET files are directed to the DefaultRedirectErrorPage.aspx file. If static content files are not handled by ASP.NET, a request for a nonexistent .html or .jpg file does not cause a redirect to the Http404ErrorPage.aspx file. If you want ASP.NET to handle requests for all file types, you can configure IIS to map file-name exten

For some reason HttpContext.Current.Server is null. I figured out where this happens: when errors occur in a user control and in my business logic classes. Am I missing something here? Thanks c# asp.net handling in asp error-handling share|improve this question edited Apr 8 '12 at 11:43 svick 124k23194305 asked Apr 8 '12 at 9:36 Peuge 69311330 2 Any reason not using Response.Redirect rather? –leppie Apr 8 '12 at 9:41 1 Where in global.asax is this? –Marc Gravell♦ Apr 8 '12 at 9:42 @leppie I did not add this so not entirely sure why the previous person chose Server.Transfer, it shouldn't make a difference though should it? –Peuge Apr 8 '12 at 9:53 @MarcGravell I have updated the question to reflect this. –Peuge Apr 8 '12 at 9:54 Earlier you use Server.blah - does Server.Transfer(...) not work?

Application life cycle is parent of Session life cycle as you can understand there can be many sessions within a single application. Thus you may have HttpContext.Current null at certain errors occured before creating session or after expiring of sessions. If you want to write session specific error redirects you should check for Null of current HttpContext always. You can also use Server.GetLastError to know the error details occured and write your error page redirect through CustomError tag in
